4 pot brake Plumbing?
coozer - 29/9/11 at 03:44 PM

Whats the best way to plumb 4 pots that have two lines into each caliper from a master cylinder with only one output?

Just a matter of splitting at the top down each side of the car then in two again into each caliper?

I have Range Rover calipers, which look exactly like Princess 4 pots, and a Suzuki SJ master cylinder

Can't see why not

That's how I'd do it.

Cheers

P.S did you ever find out how your vvt works?

Ummm! I'm stumped. Is it a recirculating system where the fluid goes in a loop to make sure any bubbles are driven off in the master cylinder or are the links between each side that are normally part of the calliper missing? I'd check the donor manual if I were you.

Cheers!

These calipers are designed for a superior split circuit design, if a single circuit fails you still have half of the front calliper pistons working which is much better than a diagonal pair (or even worse only the rears).

The Metro had a system like this, and when people used these calipers on minis the two ports were linked together with a small aeroquip pipe on the caliper. Not saying that's the nicest method though.

Two lines in, 3 bleed nipples, no external links. I know on the rangy they were a dual, split powered system but I aint going to be carrying that much weight!

Are you planning to mount them with the inlets at the bottom? You may have some bleeding issues if you dont.

You can use a kunifer pipe from the bleed nipple port on one part of the calliper to the inlet of the other part, that way you have one hose, one inlet and one bleed nipple.

And a hell of a time trying to bleed them

Not really ---- i can never understand why brake bleeding seems to cause such issues for people.

Nope, they are going back on the axle at the original position.

Nice idea, but, how do I work out which one to be sure the fluid acts on all 4 pistons? The one furthest away eg??

Coozer, this is how I remember Princess calipers were plumbed when I fitted a pair to my MK2 Escort. My brother and I realised that they were remaekably similar to Range Rover calipers, so sat some side by side to compare them. They are so close you could not see any difference, however the mountig holes were ever so slightly different ( this ruined my idea of flooding the Old School Ford market with recon Rangie calipers). Also, Range Rovers with vented discs use the same calipers but spaced from the factory, just as I had to do to fit vented discs to my Escort.

You and Brian know how to plumb them up for a single line Jon??

slingshot2000 - 29/9/11 at 08:00 PM

I will speak to Brian tomorrow, it is a while since I did them and hes till working with them every day.

Jon

Yes mate, I would appreciate that. You going to Brians tomorrow? I may have a run over in the morning to see him about the upper A arm ball joint.

slingshot2000 - 29/9/11 at 08:15 PM

Give me a txt if your going, I will be about and it would be good to see you again. I have been meaning to contact you to see if your going to Richardk's curry night.

Regards
Jon

Open the nipples and blow through with low pressure air.
